Abstract

On améliore la durabilité de valvules à trois valves en éloignant le point de contrainte maximum appliquée sur le bord libre (18) de la valve (14), de l'emplacement des facteurs d'augmentation de la contrainte. On déplace le point de contrainte maximum appliquée, en modifiant la géométrie de la courbe d'attache (16) entre la valve (14) et le corps de valvule (12). On modifie la géométrie de la courbe d'attache (16) en modifiant la forme du corps de valvule (12) ou la forme de la valve (14).
